Abstract: The objective of this note is to present the results from the two recent
papers. We study the Navier--Stokes equation on the two--dimensional torus when
forced by a finite dimensional white Gaussian noise. We give conditions under
which both the law of the solution at any time t>0, projected on a finite
dimensional subspace, has a smooth density with respect to Lebesgue measure and
the solution itself is ergodic. In particular, our results hold for specific
choices of four dimensional white Gaussian noise. Under additional assumptions,
we show that the preceding density is everywhere strictly positive.
